Will Musculoskeletal Conditions of Shoulder Affect the Hand Function and Hand-Eye Coordination? A Cross-Sectional Analysis

Abstract

Objective: To analyze the Hand Function (HF) and Hand-Eye Coordination (HEC) among subjects with shoulder conditions resulting in pain and disability. Methodology: In these cross-sectional 47 subjects with selected shoulder pathology between 30 to 60 years participated. Shoulder pathology was measured in terms of pain and disability using the SPADI scale. These values were correlated with Purdue pegboard and Balloon tossing task and Wall Ball Bounce task. Results: Spearman rank correlation analysis of SPADI pain component revealed that there was a negative correlation with HF (R= -0.596, p<0.001), but there was significant correlation with HEC1 (R= -0.260, p= 0.078) and HEC2 (R= -0.217, p= -0.144). Though there was no correlation a negative relationship was observed between the variables. In the correlation of SPADI disability component there was a perfect negative correlation with HF (R= -0.870, p<0.001), with HEC1 (R= -0.588, p<0.001) and HEC2 (R= -0.541, p<0.001). Conclusion: This study concludes that shoulder pain negatively influences the Hand Function, whereas the shoulder disability negatively influences both Hand Function and Hand-Eye Coordination. The therapist should consider assessing and treating HF and HEC in patients with shoulder pain and disability in the future.
